Hi,
that's a bug in rc6 version of cs46xx driver. The lack of bass is caused
by phase reversal of one channel, i.e. wrong sign of the values of one
channel. Therefore correlating sound (low frequency components are
stronger correlated because of the long wavelengths) in left and right
channel will cancel out more or less when using loudspeakers and the
stereophonic impression is also wrong. Up to now all reports of this
problem stated that this error occurs only with analog out, not SPDIF --
but perhaps other cs46xx based cards were used.
The cvs version should fix this problem for analog out, perhaps also for
digital out. But with cvs version SPDIF input doesn't work as it should
and did with rc6 version (at least for my Terratec XFire).
If the cvs version doesn't fix the bass problem then benny should know
what to do :-)
